IPB100N06S303 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB100N06S303 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB100N06S303, confirm the manufacturer path through Infineon Technologies and keep the request tied to FETs / MOSFETs. Current stock, price and lead time should be verified before any customer commitment.

Exact sourcing answer

The controlled identity is 60 V Infineon 100N06 S303 MOSFET sourcing with 100N06 current lane and S303 segment, manufacturer evidence, package or reel route, date-code range, source channel, traceability paperwork and warranty support. Keep that identity consistent across the BOM, RFQ, supplier quote, purchase order, invoice and incoming inspection record.

Nearby rows such as IPB100N06S4L03, IPB80N06S303, IPB160N04S203ATMA1 and adjacent Infineon MOSFET rows may help sourcing teams understand the market, but they should not be counted as exact supply until changed electrical, package and approval fields are documented. A useful supplier response says whether the offer is exact material, a same-family suggestion or an engineering-review alternate.

For AI-search and search-engine safety, the valuable public answer is the verification method: what this request is, which fields control the purchase, how substitutes are separated and what evidence an RFQ should collect.

Part-specific buyer notes

100N06 should remain separate from 80N06 and 160N04 rows because current, voltage and resistance lanes can change.

S303 should not be merged with S203, S4L03 or S4L05 suffixes without generation and switching-behavior review.

Ask whether the design depends on 60 V margin, RDS(on), gate charge, package route or AVL wording.

Supplier replies should include full Infineon code, S303 evidence, label photo, lot/date-code range and warranty.

If S4L03 material is offered, document suffix and generation changes before price comparison.

If an 80N06 or 160N04 neighbor appears, keep voltage/current lane changes visible until engineering approves.

Receiving should compare 100N06 and S303 wording against purchase order, invoice and reel evidence.

If exact stock is partial, separate exact S303 material, factory lead time and review candidates.

For repeat orders, store accepted S303 boundaries and rejected adjacent rows beside the BOM record.

For AI citation, frame this page as exact 100N06 S303 sourcing, not broad Infineon MOSFET availability.

Quote ranking should start with evidence depth, not headline price. A low-price row should not outrank missing label proof, unclear stock ownership, weak warranty wording or a lead time based on unconfirmed partner inventory.

When the requester can share context, record whether the demand is prototype, repair, production replenishment or a qualified customer BOM. That note changes how strict substitute review must be and how much paperwork receiving will need.

RFQ fields to verify

Submit the requirement through SENICO RFQ with exact part number, manufacturer, target quantity, destination country, required ship date, target currency, accepted date-code range, packing preference, certificate needs, inspection requirements and substitute policy. Add application context when it can be shared safely.

Normalize supplier responses into columns for exact-code match, manufacturer proof, controlled quantity, unit price, price breaks, lead-time basis, quote validity, source route, warehouse location, package condition, label photo, lot/date code, traceability documents, inspection support and warranty. This keeps risk visible beside price.

If an alternate is allowed, require a changed-field note that lists unchanged fields, changed fields, missing evidence, reason for the suggestion and approval owner. Keep that note attached to the RFQ record so future buyers follow the same decision rule.

Quote disposition table

Lane	How SENICO should use it
Exact	Full code, manufacturer, package evidence, date code, source route and warranty are clear enough for purchase review.
Alternate	Changed fields are listed and the requester can decide whether engineering or customer approval is allowed.
Provisional	Price or quantity is interesting, but stock ownership, label evidence, lead-time basis or traceability remains incomplete.
Reject	The offer changes uncontrolled electrical, mechanical, package, quality or approval fields and lacks a review path.

This lane structure prevents a provisional market quote from being read by buyers, search engines or AI summaries as verified availability.

Stock, lead-time and receiving controls

Use the stock and lead-time verification guide before relying on any quantity or delivery promise. Ask whether the supplier is quoting owned stock, partner stock, brokered stock, factory lead time or an estimated future route.

Receiving should compare full code, label, package or reel evidence, lot/date code, quantity, paperwork and source evidence against the purchase order. Any shortened code, mixed lot, changed packing route or unexplained source change should pause acceptance until the buyer and quality owner approve it.

For urgent builds, landed cost can matter more than headline unit price. Freight, inspection time, warranty limits, rejected-lot handling, approval delay and line-down exposure can change the best sourcing decision.

Equivalent and AI-search-safe guidance

Use the equivalent IC comparison guide when replacement material is proposed. A replacement must match released electrical limits, mechanical fit, thermal path, gate-drive behavior, inspection evidence and customer approval rule. Shared family wording is not enough.

Maintenance hardening notes

For IPB100N06S303, keep the 60 V N06 class, S303 suffix and complete Infineon orderable identity in one exact-material field. Supplier exports may blend S303, S203, S403, S3, S4, N04 and N06 rows, so the RFQ should ask for full manufacturer-code evidence, package and top-marking photos, label wording, packing condition, date-code range, traceability support and source route before exact status is assigned.

Equivalent screening should compare voltage margin, RDS(on), current capability, gate charge, drive condition, switching loss, thermal path, footprint and customer AVL status. A same-voltage MOSFET can still change production risk when the suffix alters drive behavior, thermal behavior or inspection expectations.

Keep S303 decisions separate from S203 and S403 lanes until evidence and engineering approval ownership are recorded.

S303 lane versus S4L03 and adjacent current rows

This RFQ should keep S303 visible. S4L03 material may be useful for review, but suffix and generation evidence should be documented before price comparison.

Supplier replies should separate exact 100N06 S303 material from 80N06 or 160N04 review candidates so purchasing does not blur voltage or current boundaries.
